Heat pump and method of heating fluid

摘要

A heat pump comprising an evaporator 202 that transfers heat from taken in air to a first fluid and expels the taken in air that has exchanged heat at a temperature cooler than ambient temperature, a compressor 203 for compressing and pumping the first fluid, a first heat exchanger 204 comprising a first passage for the heated compressed first fluid driven by the compressor 203 and a second passage for a second fluid driven by thermal convection, and a second heat exchanger that receives heated compressed first fluid from the compressor 203 and compressed first fluid from the first heat exchanger 204.
